je it 'known that we, 1WILLLlM l?. GAR- lnrn'on JAW/1s, citizens of the United es, residing at Bayonne, in the county oi Hudson, State of New Jersey, have invented certain new and useful lmproveniente in lrooesses for PurifyingOil; and we hereby declare the following to be a toll, clear,- and exact description of the inl vention, such as will enable others skilled the art lto which it appertains to make end use 'the same..

rilhis ine?en'tiony relates 'to a process for ying oil and has for' its object to prone means, whereby'lubricating oil may H1.. be cleaned and restoredto its former purin lied state.,

An im portant object resides in the treat'- ment o dirty and used lubricating oil,

whereby the same is purified and rendered proper condition 'for rel-use.

te es in View', the invention consists in the el conruction, arrangement and combination of parts to be hereinafter more described and claimed and illustrated the accompanying drawing, in which-n Figure l is a vertical sectional View through the oil boiling tank, Fig. 2 is a top plan view thereof, and Fig. d is a, vertical sectional viewthrough the novel purifying device. ln order to provide means whereby the oil to be treated may be puried, we provide a novel boiler structure, designated as a whole by the numeral 22 `and comprising a shell 23 mounted upon suitable legs 24e. The shell. 23 is closed at its lower end by a conical portion 25 in the apex of which is threaded e, draw-ofi cock 26, and has its upper end closed by e cap 27 provided with a plurality of openings 28. fl coil 29 formed of tubing, such as copper or the like, has one end 30 extending through the side of the l shell 23 for connection with a steam supply pipe. The steam within the coil 29, heats the' oil within the boiler 22, thus disinte- V grating the oil and the impurities carried th by. "The coil 29 extends through the greater portion et the shell 23 and has its other end 32 discharging into the atmosphere. The shell 23 is adapted to containv` oil to be purified, the oil being poured into the shell by removing the cap 27. The helght of the oil can be' seen by means of a 's1ght glass 33 f-.enneoted with the Shel1'23 by suitable 4 m acta these and other objects' and 'advan-4 connections 34 and 35, the lower connection 35 being provided with a draw-olij cock 36. After oil is poured into the shell v23, 'steam is allowed to enter the coil 29, whereupon the oil will be heated and escaping through the openings 28. After the oil has boiled a short time, the dirt and foreign matter contained therein will be loosened and will settle in the bottom of* the shell. As the boiling continues, the oil in the upper .part oi the shell will become clear first and its condition may be seen by lool;- ing into the sight glass 33. After the upper part of the oil has become sufficiently clear,I it maybe drawn olf through a draw 0H cock` 37, after which the boiling may continue.`

We have found by experience that boiling the oil about two hours is sucient to loosen up the carbon, dirt and other foreign matter mixed in with the oil. After the oil has been boiled long enough, it may be allowed to settle, whereupon the dirt and foreign matter will settle into the conical bottom 25 in the form of a sediment,` from which it -may be drawn through the cock 26, the

clear oil being drawn olil through a coclr 38. lf any appreciable amount of carbon or other undesired mattershould collect in the sightglass 33, itmay be drawn oil through the cock f36. After the oil has been thais boiled, it should be filtered. To accomplish this we provide a novel lter designated as a whole by the numeral 39 and comprising a shell d@ .eupported upon suitable legs d1. The bottom of the shell 40 is closed by a conical portion d2.' 'Disposed in the-upper portion of the shell 40 is a' pair of filtering screens d3 and Iwhicl'ofmare similar in construction,` each of which" comprises a ring e5 upon whichLH-ie disposed sheet cotton ee boiled, the vapor" placed between 'layers or preferably Turkish toweling d6. 'Silbe cotton and ton/clingI 46 is supported upon the ring l5 by a second ring i? which is scoured in plane by clamping bolts d8.

vDisposed below the ltering screen 4A is e filter i9 secured Within' the shell l0 and cornprising a' ring 50 which'carries a sheet or suitable cloth upon which is disposed a quantity of tellers earth 51. Disposed be low the ilter :formed by the n'iullers7 earth is a third filtering screen 52, identical in` conu struction with the screens i3 anglafl, and

disposed below the screen 52 is an additional iltering means 53 comprising rollers earth and identical in `i:onstrnotion with the iiten. The apex of the conical bestem 42 is" proifile Wish an cuties 5 within which is ciisgose` (zeitenE Azei the oil has been boiied, ii, is pouieii inte the ditei' 'whereupon it pass/es nrongh bhe screen 43, the seieen 44, he fniiei's earth fili/ er 9, then iu'ou'gb the esih into bhe eoniezii bottoni 42 then ont through the dischargev pipe 54.
